Abstract
A process for preparing large dimension emulsion polymer particles and the polymer products of the process are disclosed. In one embodiment, the invention provides particles having a high aspect ratio, having a shape described by a long axis and an intersecting short axis. These particles range in shape from egg-like, through rod-like, up to extended filaments. In another embodiment, the invention relates to large, nearly spherical emulsion polymer particles.
